         7 . The driving tool according to  claim 6 , wherein the elastic member is pressed against and attached to the bottom surface of the guide rail. 
     
     
         8 . The driving tool according to  claim 6 , wherein the impact receiving portion is pressed against the bottom surface of the guide rail by a force received from the pusher. 
     
     
         9 . The driving tool according to  claim 4 , wherein the elastic member has a groove that is parallel to the receiving surface. 
     
     
         10 . A driving tool comprising:
 a tool body;   a nose provided on the tool body and having an ejection port through which a driven member is ejected;   a magazine that includes a guide rail configured to guide a pusher in a feeding direction of the driven member, wherein the magazine is configured to store a plurality of driven members;   the pusher configured to push each of the plurality of driven members toward the nose;   a coupling member configured to couple the magazine to the nose, and   an elastic member provided between the nose and the magazine,   wherein the elastic member comprises:
 a protrusion configured to be pressed against a bottom surface of the guide rail of the magazine, and 
 a rattle absorbing part configured to absorb rattling of the magazine with respect to the nose and an impact receiving portion to which the pusher comes in contact when the pusher reaches an end position in a feeding direction of the driven member as a single member, the impact receiving portion having a receiving surface inclined with respect to a movement direction of the pusher of the magazine, wherein the receiving surface faces away from the protrusion. 
   
     
     
         11 . The driving tool according to  claim 10 , wherein the tool body has a driver configured to strike one of the plurality of driven members and a piston to which the driver is coupled, the piston moves in a driving direction by compressed gas generated by a movement of the piston in a direction opposite to the driving direction. 
     
     
         12 . The driving tool according to  claim 10 , wherein the magazine is coupled to the nose and the tool body. 
     
     
         13 . The driving tool according to  claim 10 , wherein the impact receiving portion further includes a plurality of grooves being parallel to the receiving surface. 
     
     
         14 . A driving tool comprising:
 a tool body;   a nose having a driver guide, wherein the driving guide has a front guide and a rear guide that are mutually coupled to each other;   a driving channel defined between the front guide and the rear guide;   a magazine that includes a guide rail configured to guide a pusher in a feeding direction of a driven member, wherein the magazine is coupled to a rear side of the nose;   the pusher having a pusher claw configured to feed the driven member toward the driving channel and a pusher holder configured to support the pusher claw;   a coupling member configured to couple the magazine to the nose; and   an elastic member,
 wherein the elastic member comprises:
